Bibble 4.3 For Windows, Mac and Linux adds lens correction (based on the excellent PTLens), support for RAW files from Nikon's D50 and D70s as well as Epson's R-D1, faster processing in the Windows version, a straightening tool and a number of other minor tweaks and bug fixes.

The Bibble Labs web site has a complete list of changes; downloads for all three supported platforms, in both Lite and Professional versions, are available here. Version 4.3 is a free update for registered users of any v4.x release.
